Current time in specified IANA timezone (e.g. 'America/New_York'). UTC if omitted.
AI agents call current_time to retrieve information from Nexus Core without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves the current time in a specified timezone. It performs a read-only operation with no side effects, data modification, or external state changes. It is purely informational and has minimal security risk even if misused by an agent.
From the tool's definition Tool name 'current_time' and description 'Current time in specified IANA timezone'. Returns time data without modification, side effects, or data manipulation.
Attacks that exploit this kind of access
Current time in specified IANA timezone (e.g. 'America/New_York'). UTC if omitted. It is categorised as a Read tool in the Nexus Core MCP Server, which means it retrieves data without modifying state.
Register the Nexus Core MCP server in PolicyLayer and add a rule for current_time: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nexus Core. Nothing to install.
current_time is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the current_time rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for current_time. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
current_time is provided by the Nexus Core MCP server (noumenon-ai/nexus-core). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
